The hidden risk in ITAD: is your data really gone?

Recent security incidents involving a compromised Python software package and critical PHP vulnerabilities have raised important questions about data security. [1][2]

But there is another question we should be asking: what happens to our data when a computer is retired?

When businesses replace their computers, old laptops and servers are often refurbished and sold. Before that happens, we need to be sure that sensitive information has been properly removed.

Deleting files or reinstalling Windows does not, on its own, prove that a drive has been securely wiped.

In IT Asset Disposition (ITAD), it's not enough to wipe a drive. We need to verify that the process has worked.

• Was the correct drive wiped?
• Was the process successful?
• Is there evidence to support the result?

It's also important to remember that wiping a drive and removing a device from an organisation's management system are two different things. Both may need to be checked before a computer is resold. [3][4]

Data security should remain a priority until the equipment has been properly checked and cleared for its next use.

For those working in ITAD and refurbishment: how do you verify that a device's data has been securely wiped before resale?
